Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific package type SOT-25 and the B-type CE pin configuration (High Active, no pull-down resistor) against system requirements. Confirm that the CE pin is driven by either VIN or VSS to prevent undefined states and increased supply current. Ensure compliance with RoHS standards as indicated by the -G suffix.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.3V output is required with high current capability up to 700mA. The B-type designation indicates a High Active CE pin without an internal pull-down resistor, requiring external drive logic. Consider the thermal dissipation limits in the SOT-25 package based on the input-output voltage differential and ambient temperature conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the XC6210 series of high current, high speed LDO regulators. The series offers selectable output voltages in 0.05V increments from 0.80V to 5.00V. The XC6210B variant specifically utilizes a High Active CE control logic without an internal pull-down resistor, distinguishing it from A, C, and D types which feature different active levels and pull-up/down configurations.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the recommended output capacitor value for the XC6210B232MR-G?

For an output voltage of 2.3V, which falls within the 1.80V to 5.00V range, a minimum output capacitor (CL) of 1.0µF is required. Ceramic capacitors are recommended.

How does the CE pin function on the XC6210B series?

The XC6210B series has a High Active CE pin with no internal pull-down resistor. The regulator turns ON when the CE pin voltage is HIGH (VIN level) and enters standby mode when LOW (VSS level). An open CE pin results in an undefined state.
